>The "price per page" has long been a efficient business model in the professional copier world.

This is true, but I'm not sure it's can be adapted for home use.

Every price per page agreement I'm familiar with involved leasing a machine and carrying a service contract. Both of those agreements make sense when we're dealing with something with a price tag of a new car that is a critical part of a business, but not so much when it costs a few hundred dollars and prints nothing more urgent than Amazon return labels.
